The G586IPB/E, equipped with a 321-pin Zero Insertion Force (ZIF)
CPU socket, is a fast Pentium processor system board supporting Intel
Pentium CPUs running at 75MHz, 90MHz, 100MHz, 120MHz, 133MHz,
150MHz and 166MHz frequencies. The G586IPB/E also supports Cyrix
P120+/P133+/P150+/P166+, AMD 5K86 75MHz, and future 200MHz
CPUs.
The G586IPB/E can support 8MB to 128MB of system memory using
EDO or fast page mode x32 DRAM. This system board also supports
pipeline burst SRAM and provides easy cache upgrade using 256KB or
512KB cache modules.
The G586IPB/E design is based on the Peripheral Component Intercon-
nect (PCI) local bus and Industry Standard Architecture (ISA) stan-
dards. It is equipped with 4 dedicated PCI slots and 3 dedicated 16-bit
ISA slots.
The G586IPB/E board has two bus master PCI IDE connectors. Bus
mastering reduces CPU use during disk transfer. This system board is
also equipped with two NS16C550A-compatible serial ports, an SPP/
ECP/EPP parallel port, a floppy disk drive controller, one PS/2 mouse
port and one PS/2 or AT keyboard connector.

Chapter 2
Hardware Installation
This chapter summarizes the steps to install the G586IPB/E system
board into your system unit. It also includes a description of the area in
which you must work and directions for memory installation. Before in-
stalling the system board, obtain the memory you plan to install. Refer
to page 13 for the number and type of SIM modules needed for the
amount of memory you require.
Preparing the Area
Before unpacking the system board, make sure the location you have
selected is relatively free of dust and static electricity. Excessive expo-
sure to dust, static electricity, direct sunlight, excessive humidity, ex-
treme cold, and water can damage the operational capabilities of your
system board. Avoid placing the unit on surfaces such as carpeted
floors. These areas also attract static electricity which can damage
some circuits on your system board.
Make sure the power source has a properly grounded, three-pronged
socket. It is essential that the power connection be properly grounded
for correct functioning of your system board. For further protection, we
recommend that you use a surge suppressor. This will protect the sys-
tem board from damage that may result from a power surge on the
electrical line.
Move items that generate magnetic fields away from your system board
since magnetic fields can also damage your system board. Once you
have selected the ideal location, unpack the G586IPB/E system board
carefully.
Handling the System Board
It is quite easy to inadvertently damage your system board even before
installing it in your system unit. Static electrical discharge can damage
computer components without causing any signs of physical damage.
You must take extra care in handling the system board to ensure
against electrostatic build-up.

10
Static Electricity Precautions
1.To prevent electrostatic build-up, leave the board in its anti-static
bag until you are ready to install it.
2.Wear an antistatic wrist strap.
3.Do all preparation work on a static-free surface with system board
components facing up.
4.Hold the system board only by its edges. Be careful not to touch
any of the components, contacts or connections, especially gold
contacts, on the board.
5.Avoid touching the pins or contacts on all modules and connectors.
Hold modules and connectors by their ends.
Warning:
Electrostatic discharge (ESD) can damage your processor, disk drives,
add-in boards, and other components. Perform the upgrade instruction
procedures described at an ESD workstation only. If such a station is
not available, you can provide some ESD protection by wearing an anti-
static wrist strap and attaching it to a metal part of the system chassis.
If a wrist strap is unavailable, establish and maintain contact with the
system chassis throughout any procedures requiring ESD protection.
Installing the System Board
If you are installing the G586IPB/E system board, the following outlines
the basic installation steps. Before installing the system board into your
system unit, you should prepare the tools you will need.
You will need:
•One medium size, flat-bladed screwdriver
•One medium Phillips screwdriver
•One needle-nosed pliers
•One nutdriver
1.Unlock your system unit. Turn off the power and disconnect all
power cords and cables.

11
2.Remove the system unit cover. Refer to the manufacturer’s instruc-
tions if necessary.
3.Remove expansion cards seated in any of the expansion slots and
detach all connectors from the old system board.
4.Loosen the screws holding the original system board and remove
the board from the system. Save the screws.
5.Remove the G586IPB/E from its original packing box. Be careful to
avoid touching all connectors and pins on the board. Please refer to
the handling instructions on pages 9-10 for proper handling tech-
niques.
6.Insert the SIMMs into the SIMM banks on the G586IPB/E. The
quantity and location of the SIMMs depends on the memory con-
figuration and type of modules you intend to use.
7.Insert the cache module, if any, into the cache module slot on the
G586IPB/E. Refer to the Cache Memory section on page 14 for
upgrading your cache memory.
8.Install the CPU. Be sure pin 1 of the CPU is aligned with pin 1 of
the socket.
9.Set the corresponding jumpers.
10.Install the prepared G586IPB/E system board into the case and re-
place the screws.
11.Reinstall all cards and connectors and replace the system unit
cover. Reconnect all power cords and cables.

System Memory
The SIMM (Single In-line Memory Module) sockets are divided into two
banks on the system board, Bank 0 and Bank 1. Each bank consists of
2 SIMM sockets.
You will need 2 or 4 pieces of SIM modules, depending on the amount
of memory you intend to install. Make sure you insert the same type of
SIMMs in one bank. You can install SIMMs in any of the banks, Bank 0
or Bank 1, but you must populate a bank first before going to the next
bank.
The G586IPB/E system board can support 8MB to 128MB of memory
using 1MBx32, 2MBx32, 4MBx32, or 8MBx32 72-pin SIMMs. The table
below shows the supported SIM modules and their corresponding
memory sizes.
SIMMs

32MB
Examples:
If you are installing 8MB of memory, you must insert two 1MBx32
SIMMs in Bank 0 or Bank 1.
If you are installing 24MB of memory, you must insert two 1MBx32
SIMMs in Bank 0 and two 2MBx32 SIMMs in Bank 1. You may also
install it vice versa by inserting two 1MBx32 SIMMs in Bank 1 and two
2MBx32 SIMMs in Bank 0.
Installing a SIM Module
A SIM module simply snaps into a socket on the system board. Pin 1 of
the SIM module must correspond with pin 1 of the socket .

1.Position the SIMM above the socket with the “notch” in the module
aligned with the “key” on the socket.
2.Seat the module at a 45° angle into the bank. Make sure it is com-
pletely seated. Tilt the module upright until it locks in place in the
socket.
Cache Memory
The G586IPB/E system board can support 256KB or 512KB pipeline
burst, direct map write-back cache SRAM. Your system board may
come with 0KB or 256KB cache mounted onboard. The 160-pin cache
module slot lets you upgrade your cache memory by installing a 256KB
or 512KB cache module.
Note:
You do not need to set any jumpers or modify the Award BIOS Setup
utility when you install the cache module.
If your system board comes with 0KB cache, you can install a 256KB or
512KB cache module in the cache module slot. If your system board is
installed with 256KB onboard cache on locations U22 and U23, you can
upgrade your cache memory to 512KB by installing a 256KB cache
module in the cache module slot. Please refer to page 12 for the loca-
tions of the cache module slot (SSM1), U22 and U23.

Warning:
We highly recommend that you use T2BSM32-256 or T2BSM32-512
cache modules. If you are using cache modules other than the ones
recommended above, make sure your cache module meet the Intel
COAST 1.3 specification. Severe damage might occur on the cache
module or system board if you insert modules other than those speci-
fied above.
Installing the Cache Module
Locate the 160-pin cache module slot on the system board. Position the
cache module above the slot. Make sure pin 1 of the cache module is
aligned with pin 1 of the slot. Carefully slide the module into the slot.
Press firmly on the top of it to seat it properly.
Note:
With the cache module installed in the cache module slot, the compo-
nents on the solder side of the add-in card in PCI Slot 3 must not pro-
trude more than 5mm. There is no limit to the length of the add-in card
installed in PCI Slot 3.

CPU Installation
The G586IPB/E allows for easy installation of CPUs. Make sure all jumpers
are set correctly before applying power or you may damage the CPU or
system board. Please see the jumper settings on the following pages.
